[][src]Struct amethyst::CallbackQueue

pub struct CallbackQueue { /* fields omitted */ }

A simple Callback queue. Using the Sender you can get using the send_handle method, you can add functions modifying World from an asynchronous context. Those callbacks will be ran sequentially without preserving ordering.

Example

This example is not tested
// First, get a `Sender` handle.
let handle = world.read_resource::<CallbackQueue>().send_handle();
// Then, create your asynchronous context (Future, Callback-based library, etc..)
let future = ...;
// Finally, use that handle inside of the asynchronous context to run code that can affect `World`.
future.on_complete(move || {
    handle.send(|mut world| world.create_entity().build()).expect("Failed to add Callback to CallbackQueue.");
});

Methods
